Title: Method for preventing oxidation of molten metal in tundish
Inventor: KIYOSE AKITO
IPC: B22D11/10
Filed: 1995-03-07
Abstract: PURPOSE: To produce an extra-low carbon steel having good cleanliness by using N2 or mixed gas of N2 and Ar as the atmosphere in a tundish to molten steel containing the specific contents of C, Ti and acid soluble Al. CONSTITUTION: The molten steel containing by mass%, <=0.005C, 0.01-0.1 Ti and <=0.1 acid soluble Al is continuously cast. As the atmosphere in the tundish, the gaseous nitrogen or the mixed gas of the gaseous nitrogen and gaseous argon is used and oxygen concn. is made to be <=2mol%. The Ti and the acid soluble Al are important elements for preventing increase of the nitrogen concn. in the molten steel. In the case of being within the conditional range, the increasing quantity of the nitrogen concn. in the molten steel becomes <=0.0001 mass %. In the case of being <=2mol% oxygen concn. in the atmosphere, the increase of the oxygen concn. in the molten steel can be restrained to <=0.0002mass% Therefore, while preventing the absorption of the nitrogen into the molten steel, the increase of the oxygen is restrained.

Filed: 1991-04-05
Abstract: PURPOSE:To form an excellnt image without rubbing an unfixed toner image by means of a guiding member at the entrance of a fixing means even in a double-side iamge formation, or even after a single-surface color image formation by lowering the output of a separating/destaticizing charger than that in one-side copying or making it zero, in double-side coplying. CONSTITUTION:The output of a destaticizing means 9 when an image is formed on the one side of a transfer material 11 and then, on its back side, is lowered than that of the destaticizing means 9 when the image is formed on one side, or made zero. Therefore, the transfer material 11 is carried up to a fixing means 7 by a carrying means 6, in a state where the back side is adhered to the guiding member, without being completely destaticized, and never rubbed by a carrying member even if it exists on the guiding member 10. On the other hand, the adhesion of the transfer material 11 after the image is formed on one side, is reduced because of reduction in flatness, so that even if the output of the destaticizer 9 is lowered, the transfer sheet 11 can be separated from the carrying means 6 by its curvature.
